Javascript encryption

[virtism]

Can anyone help in deciphering this ..

s2='';for(i=0;i< s.length;i++){s2+=String.fromCharCode(s.charCodeAt(i) ^ (i % 100));}document.write(s2)

I don't quite understand what is happening here

(s.charCodeAt(i) ^ (i % 100))

What is this ^ character doing ? can't find it in javascript operator list

Hi,

The ^ operator is "exclusive or" [en.wikipedia.org] it's a bitwise operator [developer.mozilla.org].
